我希望在點擊TextView顯示動畫之后（在動畫之后）顯示一些模態窗口。我該怎么做？Ps 我的動畫包含在 XML 文件中<animation-list>public class ExerciseWithExplain1 extends AppCompatActivity {    private Button solution;    private TextView txtVWRed, explainForTable, solExplain, nextScreen, falseRow53, falseRow54, falseRow55, falseRow56, falseRow46, trueRow45, trueRow44, falseRow43, trueRow36, trueRow35, falseRow34, trueRow33, trueRow23, falseRow23, trueRow25, trueRow24, falseRow24, falseRow25, falseRow26, falseRow33, trueRow34, falseRow35, falseRow36, trueRow43, falseRow44, falseRow45, trueRow46, trueRow53, trueRow54, trueRow55, trueRow56, trueRow26;    LinearLayout layForTable;    AlertDialog.Builder ad;    Context context;    AnimationDrawable animationDrawable;    ImageView animImage;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_exercise_with_explain1);        trueRow23 = findViewById(R.id.trueRow23);        falseRow23 = findViewById(R.id.falseRow23);        falseRow24 = findViewById(R.id.falseRow24);        trueRow24 = findViewById(R.id.trueRow24);        trueRow25 = findViewById(R.id.trueRow25);        falseRow25 = findViewById(R.id.falseRow25);        trueRow26 = findViewById(R.id.trueRow26);        falseRow26 = findViewById(R.id.falseRow26);        falseRow33 = findViewById(R.id.falseRow33);        trueRow33 = findViewById(R.id.trueRow33);        trueRow34 = findViewById(R.id.trueRow34);        falseRow34 = findViewById(R.id.falseRow34);        falseRow35 = findViewById(R.id.falseRow35);        trueRow35 = findViewById(R.id.trueRow35);
